The Role

The Infrastructure Engineer (Systems) plays a key role in architecting, deploying, and operating mission‑critical systems within a highly secured and regulated environment. As a subject‑matter expert in infrastructure technologies, the individual will design and deliver end‑to‑end secure infrastructure solutions with a focus on reliability, compliance, and resilience. The role requires a deep technical foundation across hardware, operating systems, virtualization, monitoring, backup, and log management systems, coupled with the ability to work independently under strict security and regulatory requirements.

Job Scope

• Design and implement on‑premise compute, storage, and network architectures supporting secure enterprise systems.
• Lead system integration to ensure efficient, robust, and compliant infrastructure design that meets stringent availability and reliability objectives.
• Provide technical expertise in systems architecture, evaluation, and deployment of infrastructure components including messaging, collaboration, virtualization, security, and remote access technologies.
• Lead technology evaluations and proof‑of‑concepts to assess new systems or tools for use in secured environments.
• Define standards for Red Hat, Windows Server, VMware, and Kubernetes deployments.
• Deploy and operate Kubernetes clusters (RKE2, OpenShift, or equivalent).
• Configure and manage SAN storage, including LUN provisioning, multipathing, and storage zoning.
• Implement and maintain Veritas backup, replication, and disaster recovery strategies.
• Conduct system migration, upgrades, and patch automation with minimal disruption.
• Develop and maintain Ansible playbooks for provisioning, configuration, and compliance enforcement.
• Apply policy‑as‑code frameworks (OPA, Kyverno, or Ansible Lint) to enforce configuration and security standards.
• Automate VMware, Kubernetes, and backup operations through integrated CI/CD pipelines.
• Implement CIS benchmarks and hardening standards for servers, clusters, and hypervisors.
• Configure, administer, and support SIEM platforms such as HP ArcSight, LogRhythm, or Splunk; ensure accurate capture and analysis of system and security event logs.

Job Requirements

• Diploma or Degree in Computer Science, Computer/Electronics Engineering, Information Technology, or a related discipline.
• Minimum 5 years of experience designing, deploying, and managing complex, secured IT infrastructure systems.
• Proven experience managing enterprise monitoring tools (e.g., Microsoft SCOM, CA, Riverbed), including capacity tuning and threshold optimization.
• Strong, hands‑on foundation in data centre systems, server virtualization, hyperconverged infrastructure, system monitoring, backup, and SIEM solutions.
• Expertise in Windows and Linux server installation, configuration, and administration, including patching, security configuration, and performance tuning.
• Skilled in scripting and automation using PowerShell, Shell, or Bash for system deployment and configuration.
• Demonstrated experience in high‑availability (HA) and clustered environments, including virtualization and hyperconverged setups (e.g., VMware vSphere, Nutanix Infrastructure).
• Experience managing enterprise backup solutions such as Veritas NetBackup, Commvault, or Networker, including troubleshooting backup/recovery disruptions.
• Familiar with policy‑as‑code, compliance automation, and disaster recovery architecture in regulated environments.
• Familiar with container technologies such as Docker and Kubernetes for secure application hosting, deployment, and testing.
• Certified in Kubernetes (CKA/CKAD), Nutanix (NCP), or equivalent virtualization technologies.
• Additional certifications such as RHCE, VCP, Veritas Certified Specialist, or Microsoft Server Administrator are advantageous.
